Advanced microscopy?

I don’t think this deserves that much skill. According to Smith, Smith & Weber in How to Know the Non-Gilled Mushrooms, S. floccopus has spores 9.5-15 X 8.5-12 microns vs. S. confusus, which has spores 10.5-12.5 X 9.7-10.2 microns. Of course, if talking about all the more recent species, lots of additional microscopy can assist, even electron microscopy. Even with today’s microminiaturization, EM’s still difficult to get lug into the field.

Failing an EM in the back pocket, the cap scales of S. floccopus are “large soft somewhat appressed”; and S. confusus scales are “acute, thin, rigid, erect spines or squamules…”

This looks to me more like S. floccopus, which probably is the most common Strobilomyces around, too.
